Disciotis Explained

Disciotis is a genus of fungi in the family Morchellaceae. Members of this family, characterized by their cup- or bowl-shaped apothecia, have a widespread distribution, especially in northern temperate regions.^[1]

Description

Disciotis has a cupulate (cup-shaped) pileus with vein-like hymenial folds and a small to non-existent stipe.^[2]

Species

The type species is Disciotis venosa, originally described as Peziza venosa by Christian Hendrik Persoon in 1801. Other species described in the genus include:

• Disciotis ferruginascens Boud. (
• Disciotis maturescens Boud. (1891)
• Disciotis rufescens R. Heim (1934)

It has been suggested that these species (and variants not listed above) all represent a single, morphologically variable species.^[3]

There is confusion about the names but the genus also includes these species:

• Disciotis venosa
